Description

Technical Field

[0001] The present invention relates to the technical field of lower limb arteriosclerosis warming, in particular to a warming device for patients with lower limb arteriosclerosis occlusion. Background Art

[0002] Lower limb arteriosclerosis obliterans is a disease that causes poor blood circulation in the lower limbs. It is often caused by insufficient arterial blood supply and reduced metabolic heat production, which leads to lower limb temperature, pain or intermittent claudication, and even ulcers or lower limb necrosis. Therefore, it is important to provide such patients with effective warming devices. At the same time, through the integration of temperature control sensors and App remote monitoring functions, the patient's body surface temperature can be monitored in real time, helping to detect abnormal conditions in a timely manner, providing support for treatment and care, thereby improving patient comfort and quality of life.

[0003] The warming devices for patients with lower limb arteriosclerosis occlusive disease currently widely used on the market have significant defects in providing foot protection: when the patient's feet feel overheated, the device stops heating and needs to wait for the temperature to drop. During this waiting period, the patient will inevitably feel discomfort and inconvenience, affecting their treatment experience and recognition of the product. This technical loophole not only reduces the practical effect of the device, but may also cause patients to resist due to long-term discomfort or damage their confidence in future treatment.

[0007] Preferably, both front and rear ends of the discharge frame are rotatably connected to anti-return plates, and the right end of the anti-return plate is fixedly connected to a sealing gasket, and the outer wall of the sealing gasket fits with the inner wall of the discharge frame.

[0008] Preferably, the inner wall of the anti-return plate is fixedly connected with a torsion spring 1, the other end of the torsion spring 1 is fixedly connected to the inner wall of the discharge frame, the inner wall of the shoe body is fixedly connected with a breathable pad, and the bottom end of the shoe body and the top end of the sole are fixedly connected with several exhaust nets and penetrate through them.

[0009] Preferably, the massage assembly includes a linear motor fixedly connected to the top end of the inner wall of the connecting frame 2, and a plurality of connecting bars are fixedly connected to the left end of the inner wall of the connecting frame 2, and the front ends of the connecting bars are penetrated and rotatably connected to a sleeve rod.

[0010] Preferably, the rear end of the sleeve rod is fixedly connected to a driven gear, the driving end of the linear motor is fixedly connected to a toothed plate, the rear end of the driven gear is rotatably connected to the rear end of the inner wall of the connecting frame 2, the outer wall of the toothed plate is slidably connected to the right end of the inner wall of the connecting frame 2, and the outer diameter of the driven gear is meshed with the outer wall of the toothed plate.

[0011] Preferably, the front end of the sleeve rod is provided with a connecting ball, the outer wall of the connecting ball is fixedly connected to the L-shaped rod, the outer wall of the L-shaped rod is provided with a spiral groove, and the inner wall of the left end of the second connecting frame is fixedly connected with a protruding block, and the outer wall of the protruding block is sleeved on the inner side of the spiral groove on the outer wall of the L-shaped rod.

[0012] Preferably, a thread groove is provided at the left end of each of the L-shaped rods, and the outer wall of the L-shaped rod is detachably connected to the inner wall of the massage head via the thread groove.

[0013] Preferably, the heat dissipation group includes a plurality of ring belts fixedly connected to the outer wall of the cylinder sleeve, the inner wall of the ring belt is provided with a connecting belt, and the rear end of the connecting belt is installed with a limiting ring.

[0014] Preferably, the outer wall of the connecting belt is provided with a first Velcro, and the other end of the first Velcro is provided with a second Velcro, and the outer side of the second Velcro fits with the outer side of the first Velcro.

[0015] Working principle: After the patient has completely put his leg into the sleeve and the shoe body, put one side of the connecting belt into the limiting ring set therein, and then stretch it according to the thickness of the patient's leg. Then, fit the two sides of the Velcro of the connecting belt to the Velcro at one point, so that the contracted inner diameter is limited, thereby maintaining the reliability of wearing and reducing heat dissipation.

[0016] When the patient's legs need to be kept warm, the heating wire is started to generate heat to increase the temperature of the tube sleeve and the shoe body. When the patient feels overheated, a signal is sent through the thermometer to enable the central console to start the cooling fan to rotate, thereby allowing the cooling fan to generate suction, so that the suction force on the closing plate exceeds the limiting force of the torsion spring 2, so that the closing plate is opened, allowing outside air to enter and circulate, and the air flow is discharged from the exhaust net to the sole of the shoe. When the air pressure in the sole rises, the pressure on the anti-return plate exceeds the torsion force of the torsion spring 1, so that the hot air is discharged outward. After the cooling fan stops working, the torsion spring 2 keeps the closing plate closed in the connecting frame 1, and the torsion spring 1 closes the sealing gasket at the anti-return plate in the discharge frame, so that the tube sleeve and the shoe body remain airtight again, so that the device body can quickly cool down when the patient feels overheated, thereby improving wearing comfort.

[0017] When the central console starts the linear motor in the second connecting frame, the linear motor drives the gear plate to move along the inner side of the second connecting frame, and the gear plate transmits the transmission to the driven gear, so that the sleeve rod rotates at the connecting bar, and the sleeve rod drives the L-shaped rod to move on both sides of the connecting frame. Under the action of the spiral groove on the surface of the raised block and the L-shaped rod, the L-shaped rod rotates with the cooperation of the connecting ball, so that the massage head rotates and squeezes the patient's legs, which is convenient for massaging the patient's legs and ensures smooth blood circulation.

[0018] The present invention provides a warming device for patients with lower limb arteriosclerosis occlusion. It has the following beneficial effects:

[0019] 1. After the leg is completely inserted into the sleeve and the shoe body, the present invention inserts one side of the connecting belt into the limiting ring, adjusts the tightness according to the thickness of the leg, and then fits the second Velcro onto the first Velcro to ensure that the inner diameter shrinks into place, thereby improving the wearing stability and effectively reducing heat dissipation to maintain the internal temperature.

[0020] 2. This invention activates the heating wire to keep the legs warm. When the temperature is too high, the thermometer triggers the center console to start the cooling fan. The suction force pushes open the closing plate, drawing in cool air, which is then exhausted through the exhaust screen. When the air pressure under the sole rises, the anti-return plate is pushed open to release the hot air. When the fan stops, the torsion spring resets the closing plate and anti-return plate, restoring the airtight state, rapidly reducing the temperature and improving wearing comfort.

[0021] 3. The present invention starts the linear motor through the central console, drives the gear plate to move, drives the driven gear to rotate, rotates the sleeve rod and pushes the L-shaped rod to move. Under the action of the protruding block and the spiral groove, the L-shaped rod rotates through the connecting ball, driving the massage head to rotate and squeeze the legs to massage, promote blood circulation, and relieve discomfort.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example:

[0034] like Figure 1-9 As shown, an embodiment of the present invention provides a warming device for patients with lower limb arteriosclerosis occlusion, comprising a sleeve 1, the bottom end of the sleeve 1 is fixedly connected to a shoe body 2, the front end outer wall of the sleeve 1 is fixedly connected to a connecting frame 4, the inner wall of the connecting frame 4 is connected to a cooling fan 17 through a heat dissipation component, so as to cool the temperature inside the sleeve 1, the heat dissipation component comprises a plurality of closing plates 10 rotatably connected to the front end of the connecting frame 4, the inner wall of the closing plate 10 is fixedly connected to a torsion spring 2 16, and the other end of the torsion spring 16 is fixedly connected to the shoe body 2. The ends are fixedly connected to the inner wall of the connecting frame 4, the front and rear ends of the discharge frame 12 are rotatably connected to the anti-return plate 13, the right end of the anti-return plate 13 is fixedly connected to the sealing gasket 14, the outer wall of the sealing gasket 14 fits with the inner wall of the discharge frame 12, the inner wall of the anti-return plate 13 is fixedly connected to the torsion spring 15, the other end of the torsion spring 15 is fixedly connected to the inner wall of the discharge frame 12, the inner wall of the shoe body 2 is fixedly connected to the air-permeable pad 8, and the bottom end of the shoe body 2 and the top of the sole 6 are fixedly connected to several exhaust nets 9 and pass through.

[0035] Specifically: Patients with lower limb arteriosclerosis obliterans often suffer from cold legs, pain and even increased risk of gangrene due to poor blood circulation in the lower limbs. Therefore, it is crucial to provide patients with an effective and intelligently controllable warming environment for their legs. The operating procedures and core functions of this device are as follows: First, the patient securely places the entire leg into the combined chamber of the sleeve 1 and the shoe body 2, ensuring that the foot is in the shoe body 2 and the calf is in the sleeve 1 to the required height. Then, one end of the connecting belt 18 around the leg is passed through its own limiting ring for preliminary fixation. According to the actual measurement of the patient's leg thickness, the patient or caregiver The staff can stretch the connecting belt 18 appropriately to adjust the tightness. After adjusting it into place, the Velcro 20 on the end of the connecting belt 18, that is, the velvet or hook surface part, is flatly and firmly attached to the preset Velcro 19 on the sleeve 1 or the shoe body 2, that is, the corresponding velvet or hook surface base. This operation not only achieves the reliable fixation of the connecting belt 18, but more importantly, forms a precise contraction constraint on the effective diameter of the inner diameter of the sleeve 1, ensuring that the entire device is firmly worn on the patient's leg, preventing sliding or falling off, and minimizing the heat in the internal warming space from escaping through the wearing gap, thereby ensuring thermal efficiency.

[0036] The right end of the tube sleeve 1 is fixedly connected to the connecting frame 25, and the left end of the connecting frame 25 is connected to the massage head 21 through the massage component to massage the legs worn in the tube sleeve 1. The right end of the connecting frame 25 is installed with a central console 24, and the outer wall of the left end of the connecting frame 25 is provided with a temperature detector 22. The massage component includes a linear motor 23 fixedly connected to the top of the inner wall of the connecting frame 25, and a plurality of connecting strips 26 are fixedly connected to the left end of the inner wall of the connecting frame 25. The front ends of the connecting strips 26 are rotatably connected to and penetrated by the sleeve rod 32. The rear ends of the sleeve rods 32 are fixedly connected to the driven gear 27. The driving end of the linear motor 23 is fixedly connected to the tooth plate 25. The rear end of the moving gear 27 is rotatably connected to the rear end of the inner wall of the connecting frame 25, and the outer wall of the toothed plate 25 is slidably connected to the right end of the inner wall of the connecting frame 25. The outer diameter of the driven gear 27 is engaged with the outer wall of the toothed plate 25. The front end of the sleeve rod 32 is sleeved with a connecting ball 31, and the outer wall of the connecting ball 31 is fixedly connected to the L-shaped rod 28. The outer wall of the L-shaped rod 28 is provided with a spiral groove 29. The inner wall of the left end of the connecting frame 25 is fixedly connected with a protrusion block 30. The outer wall of the protrusion block 30 is sleeved on the inner side of the spiral groove 29 of the outer wall of the L-shaped rod 28. The left end of the L-shaped rod 28 is provided with a threaded groove. The outer wall of the L-shaped rod 28 is detachably connected to the inner wall of the massage head 21 through the threaded groove.

[0037] Specifically, keeping warm is the core function of this device. When it is necessary to provide a warm environment for patients with lower limb arteriosclerosis occlusive disease to relieve the cold sensation and promote blood circulation, the built-in heating wire 11 can be activated. After being energized, the heating wire 11 quickly generates heat, evenly raising the temperature of the inner chamber of the sleeve 1 and the shoe body 2, providing warm treatment for the cold lower limbs. However, considering individual differences and possible overheating discomfort during treatment, the device has a built-in intelligent temperature control mechanism. When the patient's leg skin feels that the temperature is too high, the integrated thermometer 22 will detect the abnormal temperature rise in real time and immediately send a warning to the central console 2. 4 sends a signal. The central console 24 integrates the necessary control circuits, logic processors and power supply batteries. This is a mature existing technical support and will not be repeated here. After receiving the signal, it will respond quickly and start the cooling fan 17 located at the entrance of the specific ventilation path of the device. The cooling fan 17 starts to rotate to generate negative pressure suction. This suction acts on the closing plate 10 sealed on the channel opening. When the suction strength exceeds the rebound closing force provided by the torsion spring 16 on its fixed axis, the closing plate 10 is forcefully sucked open, thereby opening the cold air inlet from the outside, and fresh cold air is drawn in. Driven by the fan, the air enters the device and circulates, taking away excess heat. Then the air flow is discharged through the exhaust net 9 located in the sole 6 area. The exhaust net 9 is not directly external, and an anti-return plate 13 is provided at its outlet end. When the internal air pressure increases due to heat accumulation or fan drive, this pressure acts on the anti-return plate 13. When the air pressure is sufficient to overcome the torque threshold set by the torsion spring 15 on its rotating shaft, the anti-return plate 13 is pushed open, and the hot air is discharged to the outside through the exhaust frame 12 smoothly. Once the cooling fan 17 receives the instruction to stop working from the central console 24 based on the feedback temperature of the thermometer When the temperature drops to the set comfort range, the suction disappears. At this time, the torsion force of the torsion spring 2 16 immediately drives the closing plate 10 to reset in the connecting frame 4 and close it tightly. At the same time, the torsion spring 15 also pulls the anti-return plate 13 to reset, so that the sealing gasket 14 attached to it is tightly pressed against the outlet edge of the discharge frame 12, and an airtight seal is formed again. This closed-loop process allows the internal environment of the tube sleeve 1 and the shoe body 2 to quickly return to a closed and heat-insulating state. The intelligent temperature control system ensures that the device can sensitively respond to the patient's feelings and quickly cool down when overheated, greatly improving the patient's continuous wearing comfort and treatment safety.

[0038] The bottom end of the shoe body 2 is fixedly connected to the sole 6, the left end of the sole 6 is fixedly connected to the discharge frame 12, the bottom end of the sole 6 is fixedly connected to the anti-sliding block 7, the inner wall of the sole 6 is fixedly connected to the heating wire 11, the outer wall of the tube sleeve 1 is connected to the connecting belt 18 through the wearing component, so as to tighten the outer side of the tube sleeve 1, and the heat dissipation group includes several ring belts 3 fixedly connected to the outer wall of the tube sleeve 1, the inner wall of the ring belt 3 is provided with a connecting belt 18, and a limiting ring is installed at the rear end of the connecting belt 18, and the outer wall of the connecting belt 18 is provided with Velcro 19, and the other end of Velcro 1 19 is provided with Velcro 2 20, and the outer side of Velcro 2 20 fits with the outer side of Velcro 1 19.

[0039] Specifically: In order to further promote the blood circulation of the lower limbs of patients with lower limb arteriosclerosis occlusive disease, the device also integrates a massage function. When the central console 24 starts the linear motor 23 built into the connecting frame 25 as needed, such as timing or manual triggering by the patient, the motor starts working, and the output end of the linear motor 23 directly drives the gear plate 25 fixedly connected thereto, so that the gear plate 25 performs precise linear reciprocating movement along the inner track of the connecting frame 25. The linear motion of the gear plate 25 is transmitted to the driven gear 27 through meshing, causing the driven gear 27 to rotate. The rotation of the driven gear 27 is transmitted to the internal sleeve rod 32 through the connecting bar 26, forcing the sleeve rod 32 to rotate circumferentially. The rotation of the sleeve rod 32 in turn links the L-shaped rod 28 at one end thereof to start moving within the path range specified on the side of the connecting frame 25. The key is that the outer surface of the L-shaped rod 28 is precisely machined with a spiral Groove 30, and the raised block 30 in the fixed position is precisely embedded in this spiral groove 30. Therefore, when the L-shaped rod 28 is driven by the sleeve rod 32 to generate displacement, under the forced sliding cooperation between the raised block 30 and the spiral groove 30, the L-shaped rod 28 not only translates but is also forced to rotate around its own axis. This composite motion is supported by the necessary degrees of freedom provided by the connecting ball 31 joint. Finally, the massage head 21 fixedly mounted on the working end of the L-shaped rod 28 transmits the rotational transformation and linear displacement of this composite motion to the contact surface of the patient's leg. As a result, the massage head 21 simultaneously applies a dual mechanical stimulation effect of rotational kneading and circulatory squeezing to the patient's leg soft tissue. This massage that simulates professional techniques can effectively stimulate the patient's lower limb muscles and superficial blood vessels, promote local blood and lymph flow, assist in alleviating circulatory congestion and discomfort symptoms caused by arterial occlusion, and support the recovery process.
